Well I just thought I would write a post with my experience today. I had my daily shot of Tren A and Test Prop. About 30 seconds after Injection I had a tightening in my chest followed by a uncontrollable need to cough!! This was scarry as hell to me. I had read about this happening but it had not happened to me yet. I got through it and all is well now. But man was that scarry!!!! Thanks to all of your posts on the matter I didn't freak out and I stayed calm. Thanks Elite for your knowledgeable members.......38Nstrong......
